Gentlemen,
   I tried to install FreeBSD 2.2.6 onto machine with AAA-131 RAID
controller with Western Digital Enterprise USCSI 2.17G drive as drive 0
(standalone) and 3 Seagate Barracuda 2.1G drives, initiated as RAID5
array (drive 1). Primary boot assigned to WD single drive. 
   Controller detected by kernel as two devices: ahc0 (<Adaptec aic7810
RAID memory controller>) and ahc1 (<Adaptec 398X RAID controller>). When booting
kernel reports "RAID functionality not supported". After that I got normal
boot from WD drive (unit 0 at ahc1), but my RAID5 array dissasebles onto 3
single drives at ahc1, units 1, 2 and 3 consequently.
   Q: What's wrong? Is it because no RAID support for this controller in
FreeBSD or some specific tunes I have to perform to activate RAID
functionality and use RAID unit as single RAID drive?
